Class JsonRowDataSerializationSchema

java.lang.Object

org.wikimedia.eventutilities.flink.formats.json.JsonRowDataSerializationSchema

All Implemented Interfaces:

Serializable, org.apache.flink.api.common.serialization.SerializationSchema<org.apache.flink.table.data.RowData>

public class JsonRowDataSerializationSchema
extends Object
implements org.apache.flink.api.common.serialization.SerializationSchema<org.apache.flink.table.data.RowData>

Serialization schema that serializes an object of Flink internal data structure into a JSON bytes.

Serializes the input Flink object into a JSON string and converts it into byte[].

Result byte[] messages can be deserialized using JsonRowDataDeserializationSchema.

NOTE: This class was directly copied and modified from upstream Flink in order to use unshaded Jackson dependencies for use with eventutilities-core.

WMF changes from upstream Flink: - Use unshaded jackson dependencies. - added normalization function support
